Definitions

  • the present disclosure generally relates to a structural glazing spacer.
  • BACKGROUND ART Structural glazing can allow for the production of a glass facade without framing elements separating the glass panels from one another.
  • Glass panels are mounted on a respective concealed peripheral frame and then secured to the supporting structural framing. Sealing between adjacent glass panels and between the panels and the structural framing is performed by means of silicone sealant. The sealant can bond the glass panel to the structural framing to hold the glass in place.
  • Structural glazing systems make it possible to obtain continuous glazed facades in which the various glass panels are spaced from one another by very narrow gaps, having a width of the order of 15 mm, usually fully or partly occupied by a silicone sealant, which produces a regular checker-like partition among the glass panels.
  • the glass is positioned relative to the frame with a spacer, such as an extruded polymer or a foam tape.
  • the spacer maintains a gap between the glass panel and the frame which can be filled with the silicone sealant to form a strong bond between the frame and the glass panel.
  • the spacer remains within the module and can be visible through the glass.
  • a structural glazing tape can include a polymer foam tape, an adhesive layer overlying a first major surface of the polymer foam tape, and a release layer overlying a second major surface of the polymer foam tape.
  • the structural glazing tape can be used as a spacer between a structural frame and a glass panel. The spacer can provide a space for a sealant to bond the structural frame and the glass panel together.

Description

STRUCTURAL GLAZING SPACER
TECHNICAL FIELD
The present disclosure generally relates to a structural glazing spacer.
BACKGROUND ART Structural glazing can allow for the production of a glass facade without framing elements separating the glass panels from one another. Glass panels are mounted on a respective concealed peripheral frame and then secured to the supporting structural framing. Sealing between adjacent glass panels and between the panels and the structural framing is performed by means of silicone sealant. The sealant can bond the glass panel to the structural framing to hold the glass in place.
Structural glazing systems make it possible to obtain continuous glazed facades in which the various glass panels are spaced from one another by very narrow gaps, having a width of the order of 15 mm, usually fully or partly occupied by a silicone sealant, which produces a regular checker-like partition among the glass panels.
Typically, the glass is positioned relative to the frame with a spacer, such as an extruded polymer or a foam tape. The spacer maintains a gap between the glass panel and the frame which can be filled with the silicone sealant to form a strong bond between the frame and the glass panel. The spacer remains within the module and can be visible through the glass. There is an ongoing need for improved spacers that can couple the desired aesthetic appearance and ease of installation.

The polymer foam can have a force to compress at 10% in a range of about 10 kPa to about 500 kPa, such as about 50 kPa to about 300 kPa. The polymer foam can have a thickness in a range of about 2 mm to about 12 mm.
In another embodiment of the first aspect, the adhesive can be a pressure sensitive adhesive, such as a rubber-based adhesive, an acrylic -based adhesive, a silicone-based adhesive, a silylated polyurethane, or any combination thereof.

DETAILED DESCRIPTION
In an embodiment, a structural glazing tape can be used as a temporary assembly aid to create a space between a metal frame and a glass panel. The space can be suitable for applying a sealing to bond the glass panel to the metal frame. The structural glazing tape can have an adhesive on one side for bonding to the metal frame and a release layer on the other side. The release layer can substantially prevent the structural glazing tape from bonding to itself without the use of a liner when supplied in a roll.
FIG. 1 illustrates a cross-sectional view of an exemplary structural glazing tape 100. The structural glazing tape 100 can include a polymer foam 102. The polymer foam 102 can have major surfaces 104 and 106. Further, the structural glazing tape 100 can include an adhesive layer 108 overlying major surface 104 and a release layer 110 overlying major surface 106. The structural glazing tape 100 can include a barrier layer 112 between the polymer foam 102 and the release layer 110. The barrier layer can include a polymer resistant to solvents and substantially reduces or substantially prevents migration of chemicals and solvents present in the release layer 110 into polymer foam 102. The structural glazing tape 100 can further include other layers, films, or coatings (not illustrated in FIG. 1) as well. For example, the structural glazing tape 100 can further include a polymer layer, a colorant layer, U/V stabilizer layer, or a combination thereof (not illustrated in FIG. 1). The colorant layer can include a polymer and a pigment to impart and maintain an aesthetically pleasing color to the structural glazing tape 100. Additionally, a pigment in the colorant layer can substantially prevent or attenuate color changes in the polymer foam 102 due to aging, or hide color changes.
The polymer foam 102 can include a polyurethane foam, a polyvinyl chloride foam, a silicone foam, an ethylene propylene diene monomer (EPDM) rubber foam, an acrylic foam, a polychloroprene foam, polychloroprene foam, a foam blend of EPDM rubber and polypropylene, a polyethylene foam, a ethylvinyl acetate foam, or any combination thereof. The polymer foam 102 can provide a sufficient thickness to create a space between a metal frame and a glass panel so that a sealant can be applied to bond the metal frame and the glass panel together. In an exemplary embodiment, the polymer foam can have a thickness in a range of about 2 mm to about 12 mm.
Additionally, the polymer foam 102 can be partially compressible to enable the structural glazing tape to conform to the surfaces of the metal frame and the glass panel while still maintaining sufficient space between the glass panel and the metal frame for the sealant. In an exemplary embodiment, the polymer foam can have a force to compress at 10% in a range of about 10 kPa to about 500 kPa, such as about 50 kPa to about 300 kPa.
The adhesive layer 108 can include an adhesive, such as a pressure sensitive adhesive. The pressure sensitive adhesive can include a rubber-based adhesive, an acrylic -based adhesive, a silicone-based adhesive, a silylated polyurethane, combinations thereof, and the like. The adhesive layer 108 can provide sufficient adhesion to hold the structural glazing tape 100 in place during positioning of the glass panel as well as during application and curing of the sealant. In an exemplary embodiment, the adhesive layer can have a thickness in a range of about 0.01 mm to about 0.25 mm. The adhesive polymer may further include additives to impart particular properties on the adhesive polymer. For instance, pigments, fillers, catalyst, plasticizer, biocide, flame retardant, antioxidant, surfactant, tackifiers, adhesion promoting additives, and the like may be added. Exemplary pigments include organic and inorganic pigments. Suitable fillers include, for instance, silica, precipitated silica, talc, calcium carbonates, aluminasilicates, clay, zeolites, ceramics, mica, aluminium or magnesium oxide, quartz, diatomaceous earth, thermal silica, also called pyrogenic silica, and nonpyrogenic silica. The fillers may also be silicates such as talc, mica, kaolin, glass microspheres, or other mineral powders such as calcium carbonate, mineral fibers, or any combination thereof. Exemplary plasticizers include paraffinic oils, naphthenic oils, low molecular weight poly-l-butene, low molecular weight polyisobutene, and combinations thereof. In a particular embodiment, the foamed polymer includes adhesion promoting additives such as functional silanes or other adhesion promoters. Exemplary silanes include 3-aminopropyltrimethoxy silane, 3-(trimethoxysilyl)propyl methacrylate, 3- glycidoxypropyltrimethoxy silane, and n-ocryltrimethoxy silane. The adhesion promoter may optionally be used in an amount of about 0.0001 % to about 5.0%, for example from about 0.01% to about 2.0% by weight of polymer.
The release layer 110 can include a composition immiscible with the pressure sensitive adhesive. The release layer 110 can be in direct contact with the adhesive layer 108 when the structural glazing tape 100 is provided in a roll, and the release layer 110 can be easily separated from the adhesive layer 108. As such, the release layer 110 can substantially eliminate the need for a liner to be placed over the adhesive layer 108 that would otherwise need to be removed when applying the structural glazing tape 100 to the metal frame. The release agent may include a colorant or a U/V stabilizer.
For example, the release layer 110 can include a release agent, silicone-based material, a fluorine-based material, a long-chain alkyl-based material, a fatty acid amide- based material, a polyvinyl alcohol-based material, a silica powder material, or any combination thereof. An example release agent is a silicone-based release agent, such as an addition-curable and condensation curable silicone. In this type of release material, a platinum (Pt) or rhodium (Rh) catalyst is used in general as the curing catalyst for the release agent. In an embodiment, the fluorine-based material can include fluoropolymers. In one particular embodiment, the fluorine -based material can include polytetrafluoroethylene (PTFE). Alternatively, the release layer 110 can be formed of greases or oils that maintain some viscosity. For example, the release material can include a silicone grease, a fluorosilicone oil, a phenylsilicone oil, a paraffin wax, or any combination thereof.
The release layer 110 can further be formed from an aqueous precursor. The aqueous precursor includes the release agent in an aqueous medium. The release layer 110 is then formed by applying the aqueous precursor onto the surface underlying the release layer followed by dehydration of the precursor. Optionally, curing can follow the dehydration. After dehydration or curing, the release layer is formed.
Alternatively, the release layer 110 can be formed from an non-aqueous precursor. The non-aqueous precursor includes the release agent in a non-aqueous solvent. Solvents can include methyl ethyl ketone, isopropyl alcohol, acetone, toluene, methyl isobutyl ketone, or any combination thereof. The release layer 110 is then formed by applying the non-aqueous precursor onto the surface underlying the release layer followed by removal of the nonaqueous solvent. Optionally, curing can follow the removal of the solvent. After solvent removal or curing, the release layer is formed.
In an exemplary embodiment, the release layer can have a thickness in a range of about 0.003 μιη to about 50 μιη.
The release layer may also include a filler, such as a solid lubricant, a ceramic or mineral filler, a polymer filler, a fiber filler, a metal particulate filler or salts or any combination thereof. An exemplary solid lubricant includes polytetrafluoroethylene or a solid lubricant selected from molybdenum disulfide, tungsten disulfide, graphite, graphene, expanded graphite, boron nitride, talc, calcium fluoride, cerium fluoride, or any combination thereof. An exemplary ceramic or mineral includes alumina, silica, titanium dioxide, calcium fluoride, boron nitride, mica, Wollastonite, silicon carbide, silicon nitride, zirconia, carbon black, pigments, or any combination thereof. An exemplary polymer filler includes polyimide, Ekonol® polyester, polybenzimidazole, any of the thermoplastic polymers listed above, or any combination thereof. An exemplary fiber includes nylon fibers, glass fibers, carbon fibers, polyacrylonitrile fibers, polyaramid fibers, polytetrafluoroethylene fibers, basalt fibers, graphite fibers, ceramic fibers, or any combination thereof. Exemplary metals include bronze, copper, stainless steel, or any combination thereof. An exemplary salt includes a sulfate, a sulfide, a phosphate, or any combination thereof. In a particular embodiment, the release agent can be chosen to minimize undesirable optical effects when the release agent is in contact with the glass. Additionally, an exposed surface of the release layer can be textured or fillers can be incorporated into the release layer to further reduce the optical effects. FIG. 2 illustrates a cross-sectional view of another exemplary structural glazing tape
200. The structural glazing tape 200 can include a polymer foam 202. The polymer foam 202 can have major surfaces 204 and 206. Further, the structural glazing tape 200 can include an adhesive layer 208 overlying major surface 204. A polymer film 218 can overlie major surface 206. Additionally, a release layer 210 can overlie the polymer film 218.
Optionally, the structural glazing tape 200 can include a colorant layer 212 between the polymer foam 202 and the polymer film 218. In an alternate embodiment (not illustrated in FIG. 2), the colorant layer can be between release layer 210 and polymer film 218.
Polymer film 218 can include a polymer, such as a polyethylene, a polyurethane, a polyacrylate, a polymethacrylate, a polyester, or any combination thereof. In a particular embodiment, the polymer can include a polyethylene terephthalate (PET). The polymer film can include a pigment or a U/V stabilizer. The pigment can serve to substantially prevent color changes due to aging of the polymer foam 202 from being visible. Alternatively, the polymer film can be substantially transparent, and the optional colorant layer 212 can substantially obscure color changes in the polymer foam 202. Optionally, there can be an additional adhesive layer between the polymer foam 202 and the polymer film 218. The additional adhesive layer can include an adhesive suitable for increasing the adhesion between the polymer film 218 and the polymer foam 202. The additional adhesive layer can be combined with the colorant layer 212, such as by adding a pigment as a filler to the additional adhesive layer, or the additional adhesive layer can be separate from the optional colorant layer 212.
In an embodiment, the tape can be provided in a roll such that the tape can be unwound from the roll without undue force. For example, the tape can have an Unwinding Peel Strength in a range of about 0.01 lb/in to about 2.0 lb/in, such as about 0.01 lb/in to about 1.0 lb/in, or in a range of about 0.10 lb/in to about 0.5 lb/in, measured according to the force required to remove the tape directly from the roll. The Unwinding Peel Strength can be determined by measuring "T" Peel Strength at a rate of 40 inches/min according to ASTM D1876. Additionally, after removal from the roll, the tape should have sufficient adhesive strength to adhere to a surface, such as a metal frame. For example, the tape can have a peel strength from a stainless steel panel in a range of about 1.0 lb/in to about 8.0 lb/in, such as in a range of about 2.0 lb/in to about 6.0 lb/in. The peel strength from a stainless steel panel can be determined by measuring the 90-degree peel strength at 12 inches/min according to ASTM D1000-99, using a segment of tape unwound from the roll and laminated onto stainless steel panel.
FIG. 3 illustrates a cross-sectional view of an exemplary structural glazing tape 300. The structural glazing tape 300 can include a polymer foam 302. The polymer foam 302 can have major surfaces 304 and 306. Further, the structural glazing tape 300 can include an adhesive layer 308 overlying major surface 304 and a release layer 310 overlying major surface 306. Optionally, the structural glazing tape 300 can include additional layers or a coating between the polymer foam 302 and the release layer 310. The additional layer or coating can include a polymer to impart a barrier between the polymer foam 302 and the release layer 310. In another embodiment, the additional layer or coating can include a polymer including a colorant or pigment to impart aesthetically pleasing color to the structural glazing tape 300. Additionally, the pigment layer can substantially prevent color changes in the polymer foam 302 due to aging from being visible.
The polymer foam 302 can include foamed polymers, dimensions, and properties as described for polymer foam 102 in FIG. 1. The adhesive layer 308 can include compounds, dimensions, and properties as described for adhesive layer 108 in FIG. 1.
The release layer 310 can include a composition immiscible with the pressure sensitive adhesive. The release layer 310 can be in direct contact with the adhesive layer 308 when the structural glazing tape 300 is provided in a roll, and at least a portion of the release layer 310 can be easily separated from the adhesive layer 308. As such, the release layer 310 can substantially eliminate the need for a liner to be placed over the adhesive layer 308 that would otherwise need to be removed when applying the structural glazing tape 300 to the metal frame. Moreover, the release layer 310 becomes a permanent component of glazing tape 300 when placed between a frame and glass panel as further described herein.
For example, the release layer 310 can include a release agent, silicone-based material, a fluorine-based material, a long-chain alkyl-based material, a fatty acid amide- based material, a polyvinyl alcohol-based material, a silica powder material, or any combination thereof. An example release agent is a silicone-based release agent, such as an addition-curable and condensation curable silicone. In this type of release material, a platinum (Pt) or rhodium (Rh) catalyst is used in general as the curing catalyst for the release agent.
Alternatively, the release layer 310 can be formed of greases or oils that maintain some viscosity. For example, the release material can include a silicone grease, a fluorosilicone oil, a phenylsilicone oil, a paraffin wax, or any combination thereof.
Moreover, the release layer can include a solvent to modify viscosity. For release layers including a solvent, an additional barrier layer between can be present between release layer 310 and polymer foam 302 to substantially prevent migration of solvent from the release layer 310 into the polymer foam 302. The barrier layer can include a water-based polyurethane polymer. In another embodiment, the barrier layer can include an acrylic polymer, or a wax.
In an exemplary embodiment, the release layer can have a thickness in a range of about 0.003 μιη to about 50 μιη. In another embodiment, the release layer has a thickness of at least 0.3 μιη.
The release layer 310 may also include a filler, such as a solid lubricant, a ceramic or mineral filler, a polymer filler, a fiber filler, a metal particulate filler or salts or any combination thereof. An exemplary solid lubricant includes polytetrafluoroethylene or a solid lubricant selected from molybdenum disulfide, tungsten disulfide, graphite, graphene, expanded graphite, boron nitride, talc, calcium fluoride, cerium fluoride, or any combination thereof. An exemplary ceramic or mineral includes alumina, silica, titanium dioxide, calcium fluoride, boron nitride, mica, Wollastonite, silicon carbide, silicon nitride, zirconia, carbon black, pigments, or any combination thereof. An exemplary polymer filler includes polyimide, Ekonol® polyester, polybenzimidazole, any of the thermoplastic polymers listed above, or any combination thereof. An exemplary fiber includes nylon fibers, glass fibers, carbon fibers, polyacrylonitrile fibers, polyaramid fibers, polytetrafluoroethylene fibers, basalt fibers, graphite fibers, ceramic fibers, or any combination thereof. Exemplary metals include bronze, copper, stainless steel, or any combination thereof. An exemplary salt includes a sulfate, a sulfide, a phosphate, or any combination thereof. In a particular embodiment, the release agent can be chosen to minimize undesirable optical effects when the release agent is in contact with the glass. Additionally, an exposed surface of the release layer can be textured or fillers can be incorporated into the release layer to further reduce the optical effects.
FIG. 4 illustrates a cross sectional view of an exemplary structural module 400.
Structural module 400 can include a frame 402 and a glass panel 404. Between the frame 402 and the glass panel 404 can be a spacer 406, such as structural glazing tape 100, 200, or 300. The spacer 406 can include an adhesive 408 adjacent to the frame 402 to bond the spacer 406 to the frame 402. Additionally, the spacer 406 can include a release layer 410. The release layer 410 can be adjacent to the glass panel 404 when assembled within the module 400. Additionally, the structural module 400 can include a sealant 412 to bond the glass panel 404 to the frame 402. As can be seen in FIG. 4, the release layer is integrated into the structural glazing tape when the tape is deployed into a window module 400 between the frame 402 and the glass panel 404. Alternatively stated, the release layer 410 is a permanent, non-removable feature of the structural glazing tape that is directly or indirectly bonded to the polymer foam from the tape, unlike a releasable liner, which is removed prior to deployment. As should be clear, various embodiments herein are directed to self-wound tapes, having a liner- free construction and an integrated release layer in the structural glazing tape.
The frame 402 can include a metal, a polymer, or any combination thereof. In a particular embodiment, the frame can be an extruded metal or polymer. The frame 402 can provide support for the glass panel 404 and can serve as an attachment point to the structural framing of a building or other structure.
The glass panel 404 can include one or more panes of glass. In a particular embodiment, the glass panel can be a single pane glass. Alternatively, the glass panel can include two or more panes and can be an insulated glass, further serving to reduce heat flow between an exterior of the structural module 400 and the interior of the structural module 400.
The sealant 412 can include a curable polymer. In an embodiment, the curable polymer can be a moisture-cured polymer, a thermally-cured polymer, or a radiation-cured polymer. For example, curing of a moisture cured polymer can be initiated by exposure to moisture in the air. In another example, curing of a thermally-cured polymer can be initiated by heating the polymer to a curing temperature, and curing of a radiation-cured polymer can be initiated by exposing the polymer to electromagnetic radiation, such as ultra-violet (UV) radiation. In an embodiment, the curable polymer can be a silicone polymer.
After curing, the curable polymer can serve to bond the glass panel and the frame together. The adhesion of the curable polymer can be sufficient to substantially prevent the glass panel from moving relative to the frame even when the structural module is placed in a vertical position and the weight of the glass panel produces a sheering force between the glass panel and the frame. Additionally, the sealant can substantially prevent environmental elements, such as air, water, and dust, from penetrating the structural module and passing either from an interior to exterior space or from an exterior to interior space.
FIG. 5 illustrates a cross sectional view of another exemplary structural module 500. Structural module 500 can include a frame 502 and a glass panel 504. Between the frame 502 and the glass panel 504 can be a spacer 506, such as structural glazing tape 100, 200, or 300. The spacer 506 can include an adhesive 508 adjacent to the frame 402 to bond the spacer 506 to the frame 502. Additionally, the spacer 506 can include a barrier layer 514 and a release layer 510. The release layer 510 can be adjacent to the glass panel 504 when assembled within the module 500. The barrier layer 514 can be between spacer 506 and release layer 510. Additionally, the structural module 500 can include a sealant 512 to bond the glass panel 504 to the frame 502. The frame 502 can include materials as described for frame 402 in FIG. 4. The glass panel 504 can include one or more panes of glass as described for glass panel 404 in FIG. 4. The sealant 512 can include materials as described for sealant 412 in FIG. 4.
The barrier layer 514 protects spacer 506 from solvents and or liquids that are included in release layer 510. As described above, solvents may be present in release layers 210 or 110. When solvents or liquids are present in the release layers, a barrier layer, such as barrier layer 112 in FIG.l, becomes in the window module barrier layer 514 which is placed underneath release layer 510. The barrier layer 514 substantially reduces or substantially prevents migration of chemicals or solvents present in release layer 510 into spacer 506. The barrier layer 514 can include materials such as described for layer 112 in glazing tape 100. Turning to the method of forming the structural glazing tape, a release agent can be applied to a support to form a release layer. In a particular embodiment, an optional colorant layer can be applied overlying the release layer. Additionally, a polymer foam precursor can be mixed with a foaming agent and then spread onto the support overlying the release layer and optionally, the colorant layer. The polymer foam precursor can be cured to form a polymer foam, and an adhesive layer can be applied overlying the polymer foam. In an embodiment, the foam can be cut to form a tape including the release layer, the foam, and the adhesive, and the tape can be rolled onto a roll without interleaving a liner between wrappings of the tape. Rather, the release layer can serve to substantially prevent the adhesive layer from sticking to the previous wrapping of the tape.
In another embodiment, the polymer foam precursor can be mixed with a foaming agent and spread onto a polymer film, such as a PET film. The polymer film can include a release coat on the side opposite of the polymer foam precursor. The polymer film can be a colored film or a clear film. In a particular embodiment, the clear film can be coated with an optional colorant layer prior to spreading the polymer foam precursor. The polymer foam precursor can be cured to form a polymer foam and coated with an adhesive. The structure can be cut to a desired size, such as a tape having a width of between about and about 3 mm to about 50 mm. Additionally, the tape can be rolled onto a roll without interleaving a liner between wrappings of the tape. In a further embodiment, an additional adhesive layer can be located between the polymer foam and the polymer film to increase adhesion between the polymer foam and the polymer film. For example, the adhesive can be applied to a PET film and the polymer foam precursor can be applied overtop the adhesive. Alternatively, the PET film can be bonded to the polymer foam with the polymer foam after forming the polymer foam. Turning to the method of assembling the structural module, a frame can be assembled.
The frame can include an extruded aluminum. A structural glazing tape can be applied to a surface of the frame, such that the structural glazing tape only covers a portion of the surface. The structural glazing tape can be applied such that an adhesive layer of the structural glazing tape adheres to the frame. A glass panel can be applied overtop the structural glazing tape. A release layer of the structural glazing tape can be in contact with a surface of the glass panel. Due to the lack of adhesion between the release layer and the glass panel, the position of the glass panel can be adjusted as needed. The glass panel, the structural glazing tape, and the surface of the frame can define a channel. Depending on the initial positioning of the structural glazing tape on the frame, the channel can be interior of the structural glazing tape or exterior to the structural glazing tape. A sealant, such as a silicone sealant, can be applied to fill the channel. Additionally, the sealant can be cured, such as by applying heat, electromagnetic radiation, or moisture to the sealant. Upon curing the sealant can bond the glass panel to the frame.
